I guess that is true, outside of London places can get down to 7C-8C in July but that doesn't happen very often at all.. Heathrow is mostly out of the UHI and our lowest low this July was about 11C. I guess it would be better to check with a city that is not so large, though.

Europe isn't colder.

Places in Scandinavia are..

But yes, no other place on mainland Europe at sea level has 17C maxima in July and 10C mins

Exactly so we would have colder summer mins.

My weather is more like and more affected by Iceland area.

But you are also on a small island surrounded by sea, so you don't see extremes

We hit -0.6c in June before.

June isn't August. The average temperature in June is closer to September than July or August.

Here's a map of July mins in the lower 48 states:

Coastal California has a few spots of mins below 10°C (50°F). It's hard to find a 17°C/<10°C combination. Most sea level spots with mins that cold are going to have warmer maxes. Too warm in the day:

CLEARWATER, WASHINGTON - Climate Summary

This station has impressively cold summers, but that surprising given it's in a penisula jutting into the Pacific:

Point Reyes, just north of San Francisco, just under 10°C, July max 14°C. Fog-bound microclimate, a worse version of July in the western half of San Francisco:

POINT REYES LIGHT ST, CALIFORNIA - Climate Summary

Frost is unlikely in Point Reyes anytime of the year… Min almost exactly 10°C in the summer at Big Sur adjacent to the Pacific. August max is 25°C though. Same latitude as Death Valley! Again, most years don't record a frost. California coast must be a tinderbox right now, just waiting for a spark

Yes there are places on the mainland in Europe with such a climate, and not just in Scandinavia.

Murmansk - Wikipedia, the free encyclopedia

This must be one of the 20,000+ towns in Europe with coldest winters

Fort Bragg, CA is similar:

Record July low is 35°F (!) same as Murmask. Might a station issue. Nearby station with a longer record has a record July low of 38°F and a warmer average overall.
